"Within a few minutes of Holymead's departure from Riversbrook the Frenchwoman arrived. She may have passed Holymead in Tanton Gardens, or Holymead, when he saw her approaching, may have hidden inside the gateway of a neighbouring house. She had come up from the country on learning that Holymead had come to London. She caught the next train, but unfortunately it was late on arriving at Victoria owing to a slight accident to the engine. I take it that she was sent by Mrs. Holymead to follow her husband if possible and see if he had any designs on Sir Horace. She took a cab as far as the Spaniards Inn and then got out, and walked to Riversbrook. When she arrived at the house she found the front door open and the lights burning. There was no answer to her ring and she entered the house and crept upstairs. Opening the library door, she saw your father lying on the floor. She endeavoured to raise him to a sitting posture, but it was too late to do anything for him. With a convulsive movement he grasped at the handkerchief she was holding in one hand, and a corner of it was torn off and remained in his hand. When she saw he had breathed his last she laid him down on the floor. Since she had been too late to prevent the crime, the next best thing in the interests of Mrs. Holymead was to remove traces of Holymead's guilt. She picked up the revolver, which she thought belonged to Holymead, turned off the light in the room, went downstairs, turned off the light in the hall, and closed the hall door as she went out. "She behaved with remarkable courage and coolness, but she overlooked the glove in the room of the tragedy, and Holymead's stick in the hall-stand. Later in the night we have Birchill's entry into the house, his alarm at finding your father had been killed, and his return to the flat where Hill was waiting for him." When Crewe had finished he looked at the girl. She had followed his statement with breathless interest. "You have been wonderfully clever," she said. "It is perfectly marvellous." Crewe's eyes had wandered to the inlaid chess-table and the Japanese chessmen set in prim rows on either side. Mechanically he began to arrange a problem on the board. His interest in the famous murder mystery seemed to have evaporated. "I was very fortunate," he said absently, in reply to Miss Fewbanks. "Everything seemed to come right for me." "You made everything come right," she replied. "I do not know how to thank you for giving so much of your time to unravelling the mystery." "It was fascinating while it lasted," he replied, his fingers still busy with the chessmen. "Of course, I am pleased with my success, but in a way I am sorry the work has come to an end. I thought that the knowledge that Holymead was the guilty man would come as a great shock to you. But I am glad you are able to take it so well."
